Subject: [PATCH 02/10] Current I only finish the finalizable processor
 refactor.

All tests for the current semispace have passed. I've rebased to the draft pull request.
 Changes:
- I implemented process_weak_refs which is invoked by a workbucket to process weak references.
  Internally, it uses jtoc_call to reuse existing JikesRVM methods.
